STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 618,503, dated January31, 1899.

Application filed January 20, 1898. Serial No. 667,199. (No model.)

To all whom it may concern:

Be it known that we, ISAAC N. GLAUBER and JOSEPH H. GLAUBER, citizens ofthe United States, residing at Cleveland, in the county of Ouyahoga andState of Ohio, have invented certain new and useful Improvements in Stopand Vaste Cocks; and we do declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

Our invention'relates to stop and waste cocks; and the object of theinvention is to provide a stop and waste cock in the construction ofwhich provision is made for venting the waste in and through the cockitself and in which the said vent is so located in respect to thewaste-outlet that the cock can be set vertically or horizontally andvent equally well in both positions.

Hitherto stop and waste cocks have been made dependent on other meansthan those within the cocks themselves-for wasting or exhausting thepipes, and in order that the waste or exhaust might really take place ithas been necessary, first, to open the faucets or other outlets, so asto vent the pipes and then wait until the pipes were exhausted and closethem again, so as to be ready for use the next morning. Obviously to dothis in a large building like some of our large factories, where thereare many floors and many pipes with long distances to drain throughsmall holes, has been no slight inconvenience and waste of time, so thatany convenient and reliable device or construction which will save suchextra labor and time and do the work equally well is much to be desiredand is a decided improvement in the art.

Referring now to the accompanying drawings, Figure l is a centralsectional elevation of one form of our improved stop-cock with thecasing or barrel set vertically and with the'plug entering from theside. Fig. 2 is a cross-section thereof on line 2 2, Fig. 1. Fig.

3 is an elevation, partly in section, of the same construction of cockas in Figs. 1 and 2, but with the casing set horizontally and the plugentering from the top, Fig. 4 is'a side elevation, partly in section, ofa modification of the invention; and Fig. 5 is an elevation of stillanother modification, all as hereinafter fully described. These latterviews both show the cock in horizontal position, like Fig. 3, but theymay also be as seen in Fig. 1.

Having reference first to Figs. 1, 2, and 3, A represents the casing,and B the plug. The plug or valve B has the usual throughwater passage 2and waste or exhaust orifice or opening 3 at right angles thereto, andthe casing has an orifice or passage 4 in position to waste from thecentral passage2 when the plugis turned around for this purpose, as seenin Figs. 1, 2, and 3. All these parts and features are, however, old andwell known and constitute the waste-cock in common use.

Now in order to utilize this old construction for our purpose andproduce a'cock which is self-venting and requires no help or attentionwhatever, as formerly, we cast or drill an air or vent passage 5 throughthe casing and form a channel 6 in the plug in such position andrelation to the waste orifice 4 that whether the casing be placedvertically or horizontally the said vent-passage will be above or on ahigher plane than said waste-' orifice, thereby insuring a free andcertain discharge of the water from above. We have found that arelatively small difference in respective elevations will answer everypurpose and that then an inward suction is created through thevent-passage 5 instead of water flowing out at this point and the waterfrom above courses out through the wasteorifice in astream until fullyexhausted with as much safety as it formerly did when the faucets wereopened to promote the operation. 4

The channel 6 is comparatively short in the close bearing portion of theplug, so that it does not interfere with the tightness of the plug toprevent leakage, and yet has-such depth from the outer surface of thecasing that when the plug is turned to open the way through passage 2there can be no back leakage through the passage 5. Of course thechannel or groove 6 is in such position as to register with the passage5 when the wastefor use; but it is apparent that the foregoingconstruction is susceptible of various modifications without departingfrom the spirit of the invention, the idea in any case being to have avent in the cock in such relation to its waste that whether the cock belocated vertically or horizontallyavent will be opened in and throughthe body of the cock when the waste is opened and closed when the wasteis closed. Fig. 4 presents such a modification, in which the casing orbody 0 has the usual plug D and a vent-passage 7 with a self-actingvalve 8, adapted to move back and forth within slight but sufficientlimits to afford needed relief. Any equivalent and operative valvemechanism might be substituted for the one shown. Obviously if this cockwere placed vertically, as in Fig. 1. the vent would be well above theoutlet. Normally the valve 8 is seated and is open only when venting, asshown. The waste is through orifice a, central passage 1) in the plug,and orifice c in the casing, corresponding to like passages and orifices2, 3, and 4 in Figs. 1 and 2.

In Fig. 5 the casing orbody E has the usual plug F and waste-orifice d,and a vent-passage g is provided with a plug or valve h, adapted to becont-rolled by hand. This vent is located relatively about the same asin the other views, and any suitable hand-operating means may beemployed to open and close the vent-passage. Still other forms ormodifications of the invention might be suggested, but these are thoughtsufficient to show the latitude of the invention and the manydifferentforms it may assume and yet remain within the legitimate scopethereof.

The same principle of construction and use may be applied to whatisknown as a compression-stop and waste-valve mechanism or, indeed, to anyequivalent construction of valve mechanism wherein the vent may be founddesirable.

What we claim is 1. In waste mechanism for Water-pipes, the body and thevalve therein having a wastepassage, and a vent-passage in the said bodyso located as to be above the waste-outlet whether the body be setvertically or horizonrally, and having its inner end opening into thewaste-water space, substantially as described.

2. A waste-cock constructed to be interchangeable for vertical andhorizontal positions, and having a vent-passage so located as to havethe inlet end thereof higher than the waste-outlet in either and bothpositions of the cock, substantially as described.

3. A waste-cock constructed to be used both vertically and horizontallyas occasion requires, and having a vent-passage with its inner endhigher than the inner end of the waste-outlet in both positions,substantially as described.

Witness our hands to the foregoing specification this 11th day ofJanuary, 1898.
